Use the Eloquent `with()` method to eager load relationships and avoid the N+1 query problem.

When you're dealing with related models in Laravel, eager loading is a technique to load all related model data in a single query. This helps to avoid the issue where you would otherwise execute one additional query for every single item in a collection to retrieve its related models (known as the N+1 query problem).

For example, if you have a `Post` model that has many `Comments`, instead of doing this:

```php
$posts = Post::all();
foreach ($posts as $post) {
    echo $post->comments; // This causes an additional query for each post
}
```

Do this:
```php
$posts = Post::with('comments')->get();
foreach ($posts as $post) {
    echo $post->comments; // Comments are already loaded and no extra queries are made
}
```

This simple change can significantly improve the performance of your application when dealing with large datasets.
